* Engine Bay Clearance: While a 350 fits relatively well in a third-gen F-body, a 370 (which is a significantly larger displacement thanks to the bore increase) *might* require modifications to the engine bay, particularly if you're using larger accessories or aftermarket parts. You'll need to carefully check for clearance issues with the firewall, frame rails, and other components.
* Mounting: The engine mounts may need to be adjusted or replaced to accommodate the larger engine.
* Exhaust System: You'll almost certainly need a custom exhaust system. The increased size of the engine will likely interfere with the existing exhaust manifolds or headers.
* Transmission: The existing transmission might be able to handle the increased power, depending on the modifications to the 370 engine and how it's built. However, you may want to upgrade the transmission for reliability and longevity, particularly if you plan on pushing the engine hard.
* Wiring and Controls: The engine's wiring harness and computer (if it's not a carbureted setup) will likely need to be modified or replaced to match the new engine.
* Cooling System: The increased engine size will produce more heat; you may need to upgrade the radiator and cooling system components to handle the extra thermal load.
* Driveshaft: A larger engine, especially one with higher horsepower, may overstress the existing driveshaft. This may need to be replaced with a stronger unit.
In short, it's a substantial project that requires mechanical expertise and likely some fabrication skills. It's far more than just "dropping in" an engine. You'll need to plan carefully, source the necessary parts, and potentially seek help from a professional mechanic, especially if you're not experienced with engine swaps and modifications.
